Stable angina and NSTEMI: plaque distribution and target vessel vulnerability

There is very little data comparing plaque characteristics and wire-free physiological assessment in the target vessel in patients with stable angina versus acute coronary syndrome.
In this study, K. Dan et al. (USA)investigated the difference in plaque distribution between stable angina and NSTEMI, and explored the relationship between target vessel vulnerability by optical coherence tomography and wire-free functional assessment with quantitative flow ratio.
Take-home message: This study shows that plaque distribution by optical coherence tomography between stable angina and NSTEMI is similar. Target vessel vulnerability was greater in patients with lower quantitative flow ratio value.
